DDS Function Generator

DDS Function Generator
Product Detailed
uses Direct Digital Synthesis (DDS)technology perfect solution for your testing requirement 3.5-inch TFT LCD display

ATFxxB Series Function Generator(ATF10B/ATF15B/ATF20B)


ATFxxB series Function generator uses Direct Digital Synthesis (DDS)technology. Its outstanding performance and system features make it a perfect solution for your testing requirement. The simplified and optimized design of the front panel and dual-language (English/Chinese)TFT display interface make your testing much easier for operation and observation. Additionally, the extendable optional functions can also improve your system characteristics.
